Shanghai Lightning Protection Component Tester Factory | Price

The lightning protection component tester independently developed and produced by Shanghai Shengxu Electric Co., Ltd. is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors), metal ceramic two - and three electrode discharge tubes, and vacuum arresters. It can also be used as a voltage regulator, constant current power supply, and applied in other fields. It has functions such as high voltage short circuit protection, overcurrent protection, high voltage preset, range adjustment, etc., and the high voltage self discharge time is less than 0.5 seconds

Product self inspection and other:

1. Inspection of 1mA value for varistor testing

Select the "Varistor" test, turn on the high voltage, adjust the preset voltage to above 10V, short-circuit the "+" and "-" terminals of the test hole, and the display should show "000". Long press the "Display Conversion" button, and "1000" should be displayed.

2. Inspection of 0.75U1mA value for varistor testing

When the test end is open and the test button is clicked for testing, the display should show the upper limit of the range. During the green light period, holding down the "Display Conversion" button should display 0.75 times the upper limit of the range.

During the testing of the test sample, long press the "Display Conversion" button: During the U1mA measurement period, the value displayed is the test condition 1mA (1000 μ A); The value displayed during the I0.75U1mA measurement period is the test condition of 0.75U1mA.

Other functions, such as voltage preset and range adjustment, can be used as a 1999V/1mA DC voltage regulator and 1mA constant current source (the instrument outputs a constant 1mA test current when the load current reaches 1mA). When used in conjunction with the "display conversion" button, the load voltage and current (V/I characteristics) values can be measured.
